Those are exactly the 3 parameters pcb-rnd's parametric qfn() footprint 
needs:

qfn(24,5x5,0.65)

Preview and footprint:

http://igor2.repo.hu/cgi-bin/pcblib-param.cgi?cmd=+qfn%2824%2C5x5%2C0.65%29


In case you want to fine tune pads or silk: qfn() and qf() help and 
parameter description:
http://igor2.repo.hu/cgi-bin/pcblib-param.cgi?cmd=qfn&output=help
http://igor2.repo.hu/cgi-bin/pcblib-param.cgi?cmd=qf&output=help

Please double check dimensions of the footprint, I haven't used the qfn() 
on actual baords yet.

HTH,

Igor2
